In O Level syllabus, we have the flowing laws:
(a) at constant temperature, p is inversely proportional to its volume.
(b) at constant pressure, p is proportional to its temperature.
(c) at constant volume, pressure is proportional to its temperature.
all the above laws are governed by the ideal gas equation pV=nRT (which is not covered in the syllabus), where n is number of moles of the gas, R=8.31 is ideal gas constant. However, for the ideal gas equation and laws to be valid, the gas is treated as ideal gas.
One of the properties of ideal gas is that: The particles have no potential energy.

Further more, potential energy has no direct relationship with pressure.
